[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-5 The utility model provides an embodiment: a modular casting mold that adapts to the shape of the casting, including a base 1, a rotating shaft 2 is rotatably connected to the middle part of the base 1, a lower mold plate 3 is fixedly connected to the outside of the rotating shaft 2, a plurality of lower mold grooves 4 are provided on the top of the lower mold plate 3, a protrusion 5 is provided on the outer upper end of the rotating shaft 2, an upper mold plate 6 is provided just above the lower mold plate 3, a plurality of upper mold grooves 10 are provided on the bottom side of the upper mold plate 6, an injection hole 11 is provided inside the upper mold groove 10 and passes through to the outside, a limiting through hole 9 is provided in the middle part of the upper mold plate 6, and the limiting through hole 9 is slidably connected to the protrusion 5. The outer periphery of the upper mold plate 6 is rotatably connected to a top ring 7, the bottom side of the top ring 7 is fixedly connected to a top column 8, the bottom end of the top column 8 passes through the base 1 and is slidably connected to the base 1, and the bottom end of the base 1 is connected to the driving end of the electric push rod to realize automatic demoulding. The servo motor drives the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the lower mold plate 3 and the upper mold plate 6 to rotate accordingly until the injection hole 11 at the corresponding position is aligned with the injection hole 2 13, and the molten metal is poured into the closed space composed of the upper mold groove 10 and the lower mold groove 4 through the injection hole 2 13 and the injection hole 1 11 in sequence, and then cooled and fixed into shape. Then the electric push rod pushes the push column 8 to move upward, and the push column 8 pushes the upper mold plate 6 and the pressure plate 12 to move upward at the same time through the top ring 7 to achieve demoulding. Then the push column 8 moves downward, and the pressure plate 12 and the upper mold plate 6 fall down, and the limiting through hole 9 is sleeved on the protrusion 5. When it is necessary to adapt to another set of casting models, the servo motor drives the rotating shaft 2 to rotate, and then drives the lower mold plate 3 and the upper mold plate 6 to rotate simultaneously, so that the injection hole 11 of the mold that meets the production requirements is aligned with the injection hole 2 13, and then repeats the above action to complete the casting of another casting. When the shape and specifications of the cast casting change, it is automatically adjusted, without the need to frequently change the mold, thereby improving production efficiency.

[0026] The bottom end of the rotating shaft 2 is connected to the driving end of the motor, which is a servo motor. It accurately controls the rotation angle of the rotating shaft 2 and automatically adjusts to different molds to achieve production.

[0027] A pressure plate 12 is provided above the upper mold plate 6. The pressure plate 12 has the function of sealing and pressurizing the upper mold plate 6. Slide rods 14 are passed through the four corners of the pressure plate 12 to guide the movement direction of the pressure plate 12. The bottom ends of the four slide rods 14 are fixedly connected to the four corners of the top of the base 1. An injection hole 2 13 is provided on the top of the pressure plate 12, and the molten metal liquid is poured through the injection hole 2 13.

[0028] The top end of the slide rod 14 is fixedly connected to a limit block 15 , which has a limiting function to prevent the pressing plate 12 from slipping.

[0029] There are two top pillars 8, which are symmetrically arranged, making the demoulding process more stable.

[0030] Working principle: First, the servo motor drives the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the lower die plate 3 and the upper die plate 6 to rotate, until the injection hole 11 and the injection hole 2 13 at the corresponding position are aligned, and the molten metal is poured into the closed space composed of the upper die groove 10 and the lower die groove 4 through the injection hole 2 13 and the injection hole 1 11 in sequence, and then cooled and fixed into shape, and then the electric push rod pushes the top column 8 to move upward, and the top column 8 pushes the upper die plate 6 and the pressure plate 12 upward at the same time through the top ring 7 to realize demoulding, and then The top column 8 moves downward, and the pressure plate 12 and the upper mold plate 6 follow and fall, and the limit through hole 9 is sleeved on the protrusion 5. When it is necessary to adapt to another set of casting models, the servo motor drives the rotating shaft 2 to rotate, and then drives the lower mold plate 3 and the upper mold plate 6 to rotate at the same time, so that the injection hole 11 and the injection hole 2 13 of the mold that meets the production needs are aligned, and then repeat the above action to complete the casting of another casting. When the shape and specifications of the cast casting change, it is automatically adjusted without the need to frequently replace the mold, thereby improving production efficiency.
